These belonged to 34 genera and 55 species; 17 species are new to the Iberian Peninsula: Gnathia dentata (Sars, 1872); G. fallax Monod, 1926; G. oxyuraea (Lilljerborg, 1855); G. venusta Monod, 1925; Alloanthura larwoodi Wägele, 1981; Neohyssura spinicauda (Walker, 1901); Apanthuroides spathulicauda (Wägele, 1981); Aega (Aega) rosacea (Risso, 1816); Syscenus infelix Harger, 1880; Eurydice inermis Hansen, 1890; E. truncata (Norman, 1868); Natatolana borealis (Lilljerborg, 1851); Ceratothoa steindachneri Koelbel, 1878; Joeropsis legrandi Juchault, 1962; Pleurogonium variabile Schiecke and Modigh-Tota, 1976; Arcturinella banyulensis Poisson and Maury, 1931; and Astacilla gorgonophila Monod, 1925. The genus Haliophasma Haswell, 1881 was also reported for first time off the Iberian Peninsula. Another four species were new records for the Iberian Atlantic coast: Nerocila orbignyi (Guërin-Méneville, 1832); Munna limicola Sars, 1886; Astacilla axeli Castelló, 1992; and A. depressa Castelló and Poore, 1998; and five were first records for the Iberian Mediterranean coast: Paranthura nigropunctata (Lucas, 1846); Cirolana cranchii Leach, 1818; Cymodoce rubropunctata (Grube, 1864); Janira alta (Stimpson, 1853); and Arcturina rhomboidalis Koehler, 1911.
